On Black Friday — the most hectic day in retail — there are plenty of things store associates would love to tell shoppers.

But, whether it's because there's just no time or for fear of repercussions, there are some things they can't tell you.

And some of these things, while perhaps controversial, could end up being a service to shoppers or the workers themselves, if only someone would just say something.

So we asked a number of Black Friday workers to weigh in on the one thing they'd love to tell customers but can't.

We've anonymously included some of the more constructive thoughts here:

9 confessions of Black Friday workers

The deals are usually the same all day

"You're stupid if you think waiting in line at midnight means you're going to get a better price than waiting a few hours and coming later."

And they tend not to be that great

"Honestly, none of the discounts are worthwhile. A majority of the time, sale electronics are last year's or older models."

Store associates can't make secret deals with shoppers

"Don't harass employees about out of stock items or to 'let you in' on some 'special' deal you think we're hiding. We don't have the authority nor the magical savings wand to grant you that already half-off coffee maker even cheaper."

Wash all new purchases when you get home

"There's a good chance the clothes you just bought have been worn by upwards of 30 people."

Don't fall for stores' tricks to get you to spend more

"At higher end stores, don't fall for the freebie Prosecco or Pellegrino. Stores just want to keep you in there longer so you'll spend money."

"The stores are really desperate for your business, and will stop at nothing to upsell you.

"Where I worked, HQ would set next-to-impossibly high sales goals that each store was responsible for hitting. We were instructed that once we had someone on the line with money to spend, to 'keep her naked' in the dressing room and constantly bring her different colors, accessories, shoes, jewelry, Pellegrino, the works. The idea was that the more she tried on, the more you told her it look great, the more she'd spend."

Don't waste your breath

"Don't complain that you don't like the color of something to me or ask why the company no longer carries or makes a specific thing. I have literally no control over that."

Be nice or pay the price

"Black Friday shoppers tend to bang on doors, assuming that if they cause enough chaos, they will be allowed in.

"Banging on the door will make all of us hate you. As in, if there is a chance to make your shopping experience a little more difficult via small, passive aggressive actions, we will do it. Think $50 and $100 bill checks, 'a slow register', and 'Aw, we just ran out of gift wrapping.'

"All I can offer is, be nice. No one chooses to work the day after Thanksgiving."
